Some of the most extreme weather events around the world in recent years, such as the droughts in the U.S. and Australia and heat waves around the world, have been spurred by ENSO events, Wenju Cai, one of the study's authors and director of the Center for Southern Hemisphere Oceans Research at Australia's Scientific and Industrial Research Organization, told ABC News.
For this study, the researchers gathered 70 years of ENSO data -- from 1950 onwards -- and used some of the newest climate models to estimate when increased ENSO variability will be detectable in the eastern or central Pacific. They found that climate change-associated temperature increases will likely be detectable around 2030 in the eastern Pacific, four decades earlier than previously expected. The warming is also expected to occur earlier in the eastern than in the central Pacific, driven by the faster warming of this region and therefore a larger increase in rainfall.The sun sets over the Pacific ocean in Huntington Beach, Calif., Feb. 17, 2021.
